ROYALTON – A 15-year-old boy who brought a fake bomb to the South Royalton School on Thursday will face juvenile proceedings in Vermont Family Court, Vermont State Police said.

The student made the device with older radio and cellphone equipment and wires, State Police Capt. Ray Keefe said. He said the device “did resemble an explosive device to a reasonable person.”

He said troopers determined through investigation and inspection the device was not dangerous.

“It was a few inches by a few inches,” in size, Keefe told the Burlington Free Press. He said the boy admitted he had the device in his bag for much of this week.

The boy was removed from the school and was cited on suspicion of placing a hoax device and disorderly conduct, said Keefe, the state police commander in Southeastern Vermont.

Keefe said there is “nothing humorous” about a fake device.

A school administrator was advised by a student about 8 a.m. Thursday that he had seen the a picture of what appeared to be an explosive device on a computer provided to another student, Wednesday, said Keefe.

School officials viewed the student’s computer and saw pictures of what appeared to be an explosive device, police said.

The suspect’s book bag was seized and placed in a separate room, Keefe said. He said the school immediately evacuated students to the gymnasium as a precaution.

State police were summoned and began an intensive investigation to ensure the safety of students, faculty and staff in the building on South Windsor Street, police said.
